To allwhom itmay concern:

Be it known that I, CARL A. JoERrssEN,

- citizen of the United States, and resident of machine may be resented in different relatlve positions to t e striking bars in order to utilize the the ribbon, to economize in bon, or to print through the medium of different printing colors, and to return the rinting colors to the same normal osition ol rest at all times in order to avoi interfering -with the sightwritingfeature of the machine; also to have these operations take place'both with up er and lower case writing. p p

n carryin out my invention, 1- rovide' means whereby the mechanism whic intropoint of the type entire surface of the use of the ribduces, the ribbon between the type and the- -platen at each stroke of the machine,'is made to vary the throw of the ribbon in some suitable manner, for instance by moving it a reater or lesser transverse distance to bring different portions of a single color ribbon, or the differently colored portions of a polychrome ribbon over the rinting point.

In the embodiment SEBIGGtGCl in the present case, for the purpose of illustrating my invention, the point of enga ement between the actuating member, an the connection or lever through which the ribbon guide is moved, is shifted so that the throw imparted to the ribbon isamplified or reduced according to the ortion of the ribbon upon which it is desired to have the type strike such connection being established preferably through means of studs or pins on the ribbon interposing means cbrresponding in number to the colors or different transverse portions'of the ribbon to be interposed, and an actuator mounted on a part which q'eciprocates in the normal operation of the machine andwhich shifts in the operation of changing fi'om lower to upper case writing, said actuator enga ing the pins or studs through means 0 s ots which permit the case shifting motion Without chan ing the control of the actuator over;

the ribbon interposin means and being 1votally mounted so that it may be move to bring eit-her oft-he slots into engagement with Specification 0 1 Letters Patent; Application filed April 14, 1905. Serial No. 255,634.

a stud or pin at will.v The actuator is thus adapted to determine by engagement with the appro riate pin or stud which of the printing co ore is interposed over the printing a point. But other methods of placing differ ent arts of theribbon over theprinting point whilb returning the ribbon to the same initial.

or normal position of rest, may be employed without departing from the broad spirit of my invention.

My present invention further relates to means whereby the aforesaid varying of the throw (whether by amplifying the throw or by otherwise changing it) may, at the will of the-- operator, be adjusted so as to require separate or inde endent manual setting, as when using a po ychrome ribbon, or may be adjusted so that the change is accomplished automatically or in consequenceof the shifting of the ribbon feed, as for using up the entire ribbon. That is to say, the same machine, for the purpose of economizing in the use of a single color ribbon, may be made to automatically vary the throw of the ribbon with the chan e of the ribbon feed and may be convenient j chrome, so that as desired. 7

In the accompanying drawings, the inventioii is illustrated as appliedto a ty ewriter front strike si ht writing of a wel known type, but it w' I be obvious that with minor changes in details of construction, it may be used with other classes or ypes of sight writing typewriters In said drawings, F igure 1 is a vertical sectionof the writing machine taken from front to rear in the planeof the ribbon uide. Fig

.2 1s a vertical transverse section in the plane a detail perspective view 0 the means for shifting the connection-bet een the ribbon guide and the part which actuates-it. Figs. 4 and 5 are detail views illustratin the differ-' ent throws impa'rted to the rib on guide,

of the-ribbon shifting mechigiism. Fig. 3 is when the actuating connection is in its different positions. Fig. 6 isa detail view of the connection whereby the ribbon varyin means is connected with the ribbon shift mechanism. Referring to Fig- 1, 1 represents the printing roll or platen of the paper carriage and 2' which is mounted to move vertically on a adjusted for using a polythe varying of throw and consequent change of color, will occur only 3 is the ribbon guide fixed part 4 of the machine and is raised by riage shifting frame 8 which is fulcrumed at 9 order to strike upon a lever 5 in order brought into e and actuated in a known manner. 10 represents a slotted arm which is secured at 11 to a frame 12 which is moved from front to rear eachtime a key lever is depressed and said arm 1O engages a pin 13 on the upperend of to impart the necessary movement to the ribbon guide 3. As-thus far described, the parts are of a well known' construction.

In carrying out my present invention ac.- cording to the embodiment here shown it is desired to amplify the vertical movement of the ribbon guide 3 while returning it at all times to the same normal position of rest, different portion of the ribbon which passes stance for the purpose of using up the entire ribbon surface or for writing on differently colored ortions of the ribbon. T o accomplish this end, the slotted arm 10 is made ifurcated as shown ditional pin 13 the pin '13, and lever.

nearer to its fulcrum 7 than to bring eitheli; itls slotted side 10 into en a ement wit t e in l3 ,1 'or its 0 osite s lo tted side 10 with the pin 'lifi pp relative distances of the pins 13 and 13 from the fulcrum 7 of the lever 5, it is obvi ous that the throw of the ribbon guide 3 will be amplified or reduced accordingto which pin-is engaged by the, rocking arm 10. The difference. between the throws thus imparted to the guide '3 is illustrated in Figs. 4 and 5.

In orderto rock the arm 10 upon its pivotal connection 11, said arm is provided with a tail-piece 14 extending downwardly and having suitable connection with a longitudin'ally shiftable rod 15 which may be conveniently mounted in the side frames of the machine. consists of a pair of flanges 16 on the rod 15', between which the tail piece14 extends, so thatas the rod 15 is shifted longitudinally, either side 10 or 10 of the arm. may be ngagement with the corresponding pm at wil I 'When a polychrome ribbon is used, the rod 15 will 'be shifted one way or the other according to the color of writing desired.

In order to make'the varying of the throw of .the ribbon guide follow the shifting of the ribbon feed, the ratchet lever 17 of the com-v mon form of ribbon shift 15 provided with an upwardly and rearwardly extending arm 18 I through the guide, at... different strokes of the machine, as for inmore clearly in Figs. 21 and 3, and the lever is provided with an adon the opposite side of they Arm 10 is moreover pivoted at its connection 11 with the reciprocatingframe 12",\ so that it may be rocked'on said connection.

From the The connection here. illustrated 7 which enters between the flanges, 16. As

will be seen from Fig. 2, the ratchet lever 17 carries the dogs 19 which'engage the ratchet wheels 20 of the ribbon feed of well-known construction and with my improved connec tion between the lever 17 and the ribbon varying mechanism, it will follow that each time the ribbon is wound upon one spool, during which the writing has been along one edge of the ribbon, and the connections are shiftedso "as to wind the ribbon upon the other spool, the ribbon guidewill be amplified in its movements-during the succeeding run of'the ribbon so that the writing takes.

laee in a different line from before. In order that this automatic shifting of the ribbon amplifying meansv may be thrown out, the flanges 16 are provided with recesses 21 which by turning the rod 15 may be brought in alinement with the upward extension 18, so that the latter will then have no effect upon the. rod 15 or parts controlled thereby, while the control of said rod over the actuating connections ofthe ribbon guide will remain unimpaired. 1

The ribbon, it will be understood, is to be arranged in a known manner and. is to pass through the ribbon guide in a way that is common to machines of the type selected for illustrating the present invention. The ribbon is illustrated longitudinal zones upon which the stroke of the type is delivered in consequence of changi ng the throw of the ribbon, are illustrated by a, and a. These longitudinal ortions of the ribbon may be of different coibrs as in well lgnown forms of polychrome typewriter ribons.

Havingthus described my invention what I claim and desire to secure by Letters Pate ent is:
